Hi. My Mazda famaly car has some sort of problem and I can't figure it out. Sometimes when I push the accelerator the car moves very slowly, no matter how hard I push it, it moves slowly and shakes back and forth, than it suddenly takes off. It also make a pooping sound when this happens?

Do you have a check engine light?

Check the exhaust system for restriction and the transmission for slippage-start here

Field test-disconnect the exhaust pipe from the exhaust manifold hang it to the side and test drive it-
